I am sending an email in HTML format using Java mail.
In this I have included an image using
<img />

the mail is going fine usng java mail api

If I view this email from my system, I am able to view the image (it seems to be picking the local path). but when I open this email on some other system, email does not display.

Can someone please let me know how to embed the image so that it opens on other system as well.

My code is as follows

public static void main(String[] args) {
 
 String to = "ee@3l.in";
 String from = "r22@rr.com";
 String host = "127.0.0.1";
 Properties props = new Properties();
 props.put("mail.smtp.host", host);
 props.put("mail.debug", "true");
 
 Session session = Session.getInstance(props);
 try {
 Transport bus = session.getTransport("smtp");
 bus.connect();
 Message msg = new MimeMessage(session);
 msg.setFrom(new InternetAddress(from)); 
 InternetAddress[] address = {new InternetAddress(to)};
 msg.setRecipients(Message.RecipientType.TO, address);
 msg.setSubject("firmation");
 msg.setSentDate(new Date());
 
 
 Multipart mp = new MimeMultipart();
 
 
 setHTMLContent(msg, mp);
 msg.saveChanges();
 bus.sendMessage(msg, address);
 
 bus.close();
 
 }
 catch (MessagingException mex) {
 mex.printStackTrace();
 while (mex.getNextException() != null) {
 Exception ex = mex.getNextException();
 ex.printStackTrace();
 if (!(ex instanceof MessagingException)) break;
 else mex = (MessagingException)ex;
 }
 }
 }
 
 
 public static void setHTMLContent(Message msg, Multipart mp) throws MessagingException {
 
 String html = "<HTML><head><style></style></head>";
 html = html + "<BODY>Dear Mr ABC,";
 html=html+"[i]<img />[/i] ";
 html = html + " Regards tha </BODY></HTML>";
 
 MimeBodyPart p1 = new MimeBodyPart();
 msg.setContent(mp);
 p1.setContent(html, "text/html");
 mp.addBodyPart(p1);
 
 
 }

I also tried this but no good

public static void setHTMLContent(Message msg, Multipart mp) throws MessagingException {

MimeBodyPart p1 = new MimeBodyPart();
 
 /*****/
 DataSource fds = new FileDataSource("C:\\images\\clip_image002.jpg");
 p1.setDataHandler(new DataHandler(fds));
 p1.setHeader("Content-ID","<image>");
 /********/
 String html = "<HTML><head><style></style></head>";
 html = html + "<BODY>Dear Mr ABC,";
		html=html+"<img > ";
 html = html + " Regards tha </BODY></HTML>";
 
 MimeBodyPart p1 = new MimeBodyPart();
 msg.setContent(mp);
 p1.setContent(html, "text/html");
 mp.addBodyPart(p1);
 
 
 }

<img> displays nothing without a src attribute.

You can include images in two ways:
1) as a link to a remote website. The src must point to the absolute URL of the image: <img src="https://coderanch.com/path/image.png">;
Note that most email clients have options to not download these images until the user explicitly tells the client to download them.

2) as an inline image. The image is a special kind of attachment.
Now you can possibly do this with JavaMail, but to be honest, I don't know how. You may want to use Aoache Commons Email; the HtmlEmail class has several embed methods. The example from the HtmlEmail class' API:
This will embed two images: the my/image.gif image, and some PNG image.

>> displays nothing without a src attribute.

"src" attribute was there in the tag but it did not display after posting.

Ah ok. Still, the rest of my post still holds (except the img tags, but the API page will show you the full code).
